IMPROVED TUG-TRIMMER.

TO ALLr WHOM IT MAY CONCERN:

Be it known that I, ALBERT V. HILL, of Limestone, in the county of Cattaraugus, and State of New York, have invented a new and improved Tug-Trimmer; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in'thevart to make and use Ithe same, reference being had to the accompanying drawings, forining part of this specification, in which-- Figure 1 is a top view of my improved tug-trimmer.jrr

Figure 2 is a detail cross-section of the saine taken through th'e line :z: 2:, fig. I.

Similar letters of refercnce'indicate like parts.

My invention has for its object to furnish an improved Vinstrument by means of which the edges of a. tug may be conveniently, accurately, and quickly trimmed; and it consists iu the angle knives and adjustable blocks, in combination with the adjusting-screw and frame, having a scale marked upon it, and in the combination of the roller, roller-frame, and screws with each other and with the main frame of the instrument, the whole being constructed and arranged as hereinafter-more fully described.

A is a U-shaped frame, to the ends of the arms of which is secured a cap, B, havinga hole through its .centre for the reception of the screw C, which passes through it ini such a way that while free to turn it can neither move forward nor back. The forward end of the screw C rests and revolves in a socket in the other,` end of the frame A. D is a crank attached to the outer end of the screw, by means of'which it is operated. E is a block secured to the end of the frame A by a screw or screws, and the inner side of which is notched, as

Ashown in `the drawings, to allow the shavings to escape readily. F is a block Asimilar iu construction to the block E, except that its lower part is extended down through the opening in the frame A, and has a hole formed through it for the passa-ge of screw C, said hole having'a screw-thread cut in it corresponding with the thread of the said screw, so that by turning the screw C the'block F may be moved forward or back to adjust it to the required widt'h of the tug. To enable this to be done quickly and accurately a scale is formed upon the frame A, as shown in g. 1. G'r are thc knives, which are bent at right.angles-that they may be attached to the ends of the blocks E and F, and project along their sides in proper position 'for trimming the cdgcs of the tugs as they are drawn through the machine. II is a frame, to the end bars of which, beneath thc longitudinal bar, is pivoted the'rollerI to hold the tug down close to the frame A as it is drawn through the machine. The roller I is held down toits place and enabled to adapt itself 4to .the thickness of the various tugs by the coiled wire springs Jcoiled around the cud bars or screws of the frame II and prcssing against thc longitudinal bar of said fraure, as shown in iig. 2.

What I claim as new, and desire to A.secure by Letters Patent, is-V 1. The knives G and blocks E and Ii, in combination with the adjusting-screw C and frame A, having a scale marked upon it, substantially as herein shown and described and forthe purpose set forth.

2. 'lhe combination of the roller I, roller-frame H, and coiled springs Jwith eachother, and with the frame A, substantially as herein sho-wn and described and for the purpose sot forth.
